With the increasing market share of retailer brands, many authors have paid considerable attention to retailer brands. Before market liberalisation in 1996 in Korea, retailer brand market was led by the supermarket retailing format, although the first retailer brand product was developed by the department store format. In parallel with the entry of foreign multiple retailers, the retailer brand market has experienced rapid growth. Particularly, the expansion of Tesco UK with well-established retailing know-how into Korea has encouraged Tesco Korea to actively get involved in retailer brand program. As a result, Tesco Korea has led retailer brand market in the Korean marketplace. The research starts with the question of why Tesco Korea has achieved such a higher retailer brand share. Accordingly, this study is to explore how Tesco UK has transferred its own retailing knowledge into Tesco Korea, in terms of retailer brand program development. In order to explore why the retailer brand share of Tesco Korea is higher than that of its counterparts, the author adopted in-depth interview with prepared-questions and store observation as a research methodology. To examine working process as well as information flows within Tesco Korea and from UK to Korea, in-depth interview method is one of the most suitable research methodologies, because of the difficulty of quantifying information or data related to work flows. In addition, to increase the validity of information, the researcher had interviews with Tesco Korea supplier and store personnel. Based on these research techniques, this research explored how Tesco UK has influenced or advised Tesco Korea, particularly, from the point of view of knowledge transfer. Since the entry of Tesco UK into Korea as a joint-venture, the retailer brand market share of Tesco Korea has continuously increased. It would be expected that Tesco UK has helped Tesco Korea to settle down in the Korean market. During interviews with Tesco and a Tesco supplier, the researcher found that Tesco Korea has obviously taken an advantage of retailing know-how created by Tesco UK. Furthermore, the retailer brand development and handling process of Tesco Korea has been operated with the help of Tesco UK. This might mean that Tesco UK has directly or indirectly an impact on the improvement of Korean retailer brand development skills. As a mechanism to transfer retailing knowledge developed in the home market into the host market, one of the international retailers, Tesco UK has adopted many different ways such as annual meeting, trading meeting to import or export own retailer brand products, offering of operation manual developed by Tesco UK and buyer cooperation between Tesco UK and Korea, in order to share information. Through these communication techniques, the knowledge of Tesco UK has been transferred to Tesco Korea. This research accordingly suggests that retailer brand market share is apparently related to how sophisticated or advanced the knowledge of the retailer brand development and handling process of retailers are. It is also demonstrated by this research that advanced development and handling skills make a considerable contribution to increasing retailer brand share in markets with a lower share or no presence of retailer brands.

An objective index for quality estimation of anchovy sauce, our traditional seafood, has been required because inadequate standard causes dispute about quality estimation. Qualities of anchovy sauce made by traditional method and commercial anchor sauce products were compared by investigating their proximate compositions, total nitrogen contents, amino acid contents, development and level of a specific peptide on SDS-polyacrylamde gel electrophoresis (SDS-PAGE) and isoelectric point (pI) of the specific peptide. Also, pIs of IEF were attemped to identify fish species of salt-fermented sauces. The 55,600 and 46,900 dalton of peptide band were identified in all experimental samples. Especially, the area of 55,600 dalton was closely correlated with total nitrogen contents. Also, specific pIs in accordance with fish species were identified. The results suggest that correlation between area of 55,600 dalton and total nitrogen contents are used of index for quality estimation, and specific pIs are used of fish species identification.

Purpose - The TOEIC test has been leading the change in the quality and the globalization of companies for about last 30 years. The TOEIC test is taken by about two million people each year and is used as a criterion to select new employees in companies or government offices, for performance ratings, and for overseas posting selections. Universities also use TOEIC test in various ways. Since the TOEIC test is used for the selection of new students for admission, transferring extra credits, scholarships, graduation certification, and admission of international students studying abroad, many universities all over the country provide students with TOEIC study lectures through their own language institutes. Despite the fact, there has been no research on the service quality or even the current situation of these institutes. Thus, this study aims to evaluate the factors that impact TOEIC lecture service quality and analyzes the effect of the expectation related to the education service quality and the result of education on intentional behavior. Research design, data, methodology - Data was collected by administering a survey to current TOEIC students from different university language institutes. The survey questionnaire comprised of a five-point Likert scale. The demographic analysis was conducted using the frequency analysis method and the factor analysis was conducted to verify the validity of questionnaire over any variable. The reliability analysis was conducted to verify the reliability of the results. Besides, multiple regression analysis, regression analysis, and mediated effect verification were also conducted. For education service quality, four different independent variables such as reliability, response, conviction, and sympathy were considered using the SERVQUAL survey model. Based on the research models, the study hypotheses below were formulated in order to recognize an effect relationship between the variables. The four hypotheses are, "the hypothesis on education service quality and TOEIC study result expectation," "the hypothesis on education service quality and behavioral intention," "the hypothesis on study result expectation and behavioral intention," and "the hypothesis on study result expectation and mediated effect." Results - The results are as follows. First, the factors like response, conviction, and sympathy have a positive influence on TOEIC study result expectations. Second, the TOEIC study result expectation has a positive influence on the factors of behavioral intention such as re-sign up, positive word-of-mouth, "loyalty towards school." Third, it was verified that the mediated effect on behavioral intention was influenced by education service quality at university foreign language institute, while the study result expectation has only a partial mediated effect. Conclusions - The implications of this study are summarized as follows: First, it suggests a new research model for the effect of the expectation related to the education service quality and the result of education in the university language institutes on the behavioral intention. Second, it has established a relationship between the education service quality and study result expectation by verifying the mediated effect on them.

Purpose - The purpose of this study was to clarify the factors to make an exclusive importation contract between foreign fashion brands and local retailers for successful business in Korea. Even though imported fashion brand market shows stead increasing in terms of sales amount, the number of store related study was very rare in fact. Meanwhile, as long as this business is glowing a lot of brands are suffering from bad business performance or getting in ruins thus these problems result in foreign currency loss. The local marketers therefore, strongly expect to know the solution for this matter. Research design, data, and methodology - For the qualitative research, 10 experts who are operating foreign brands with an exclusive contract at a department store or at duty free shop now and who had at least over 10 years of related working experience were included. The factors for the exclusive importation contract with foreign brands were drawn up through the one-to-one in-depth interview method from September 3, 2017 to January 15, 2018. The expert group for the validity analysis includes 2 professors and 5 postgraduate students. Results - As a result of qualitative study on the factors for imported fashion brand's launching with the exclusive importation contract, it turned out that there were 5 factors - safety, profitability, reliability, speed and global retailing. Safety, profitability, and reliability have been mentioned in most related surveys but some details are added and speed and global retailing have been newly highlighted and many unknown legal issues that it was not easy to get form common academic research are included. Speed simply means quick lead time and global retailing means stores where located in other countries. Conclusions - The reason that qualitative research should be done before the quantitative research is due to the scant theoretical background for this matter. Because the market of an imported fashion brand is steadily increasing, determining the factors to make exclusive importation contract is very meaningful from the point of academic and business. After this study, many marketers may get basic conditions to apply for real business and I hope the following quantitative research will give more effective results. The next study also will have extended range concerning industry area, product and distribution channel.

In this paper, the methods to measure the mean age at first marriage is examined, and by analysing data of Korean women for the period 1970-1990, the differences that each methods make on measurements of the mean age at first marriage are presented. The main findings were : The Hajnal's SMAM, the most used index in studies of the pattern of marriage in Korea, was not a measure based on the marriages for a specific period. The resulting biases, in cases of 1970-1990 Korean women, were below 0.3 year in age, which can be considered small, if the changes in the pattern of marriage in these periods took into account. But the possibility of bringing larger bias cannot be excluded. Also the direction of biases was toward raising the mean age when marriage was in upward tendency. Considering the availability of data in Korea, the utilization of the simple mean or the measure from Agarwala method according to the purpose is recommendable. The mean age at first marriage by Agarwala(ASMAM) meets with the one computed from a gross nuptiality table based on the cohort's marriage rates for a specific period. The time series of the proportion single by age groups obtained from the population censuses showed high consistency. However when they were compaired with those computed from sample surveys at a same point of time, significant differences(at $\alpha$=0.05) were found in some major age groups. It was also pointed out that these differences were not caused by the problems related with the sampling frame for surveys or the survey questions.

Digital Multimedia Broadcasting(DMB) is a reliable multi-service system for reception by mobile and portable receivers. DMB system allows interference-free reception under the conditions of multipath propagation and transmission errors using COFDM modulation scheme, simultaneously, needs powerful channel error's correction ability. Viterbi Decoder for DMB receiver uses punctured convolutional code and needs lots of computations for real-time operation. So, it is desired to design a high speed and low-power hardware scheme for Viterbi decoder. This paper proposes a combined add-compare-select(ACS) and path metric normalization(PMN) unit for computation power. The proposed PMN architecture reduces the problem of the critical path by applying fixed value for selection algorithm due to the comparison tree which has a weak point from structure with the high-speed operation. The proposed ACS uses the decomposition and the pre-computation technique for reducing the complicated degree of the adder, the comparator and multiplexer. According to a simulation result, reduction of area $3.78\%$, power consumption $12.22\%$, maximum gate delay $23.80\%$ occurred from punctured viterbi decoder for DMB system.

This study shows the test results of seven RC beams retrofitted with modified polymer system and parametric study about the effects of tensile strength of retrofitting materials by analytical method on the flexural behavior. The main parameters are the retrofitted depth and length. The beams are loaded to the failure by four-point loading. Test results show that the effect of the retrofitted length on the structural behavior is more significant than that of depth. As the retrofitted depth is increased, the beams represents the brittle failure mode The non-linear analysis is carried out to grasp the effect of the tensile strength of retrofitting material on the structural behavior. As the retrofitted depth and length are increased, the tensile strength becomes more effective so these parameters should be considered to determine the retrofitted area. The analytical results show that failure strength is less than that of experimental results, but the stiffness is vice versa.

This study attempted to analyze the distribution of stress, to examine the bending effect in the mandible according to the pulling directions and determine on which pulling directions are adequate when an orthopedic force was applied to the mandible. An orthopedic force, 500gm, was applied to the gnathion, one point of the chin area, in three directions. The three directions were ; high puli' from gnathion to the center of condyle head, and vertical pull, from gnathion to a parallel line with the posterior border of the ramus, and medium pull, from the gnathion to a parallel line with the lower border of mandible. The distribution of principal stress, bending moment and amount of displacement within the mandible was analyzed by a 3-dimensional finite element method and that of the various portions of mandible were computed and compared according to the pulling directions. The results were as follows : 1. The bending moment of each part of a mandible has been found to be markedly larger in case of vertical pull than in case of either high pull or medium pull. In vertical pull the bending moment turned out to largest at the condyle head and neck portion, the gonial angle portion, the coronoid portion and the ascending ramus portion, respectively, while comparatively large at the cuspid and bicuspid portion and the first molar portion. In case of high pull it was largest at the gonial angle portion and becoming smaller at the coronoid portion, the ascending ramus portion, the condyle head and neck portion, and the cuspid and bicuspid portion, in that order. In case of medium pull, however, the bending moment was largest at the condyle head and neck portion, becoming smaller at the first molar portion, the ascending ramus portion, the coronoid portion, the cuspid and bicuspid portion, and gonial angle portion, in that order. 2. As for the bending effect it was calculated to be mostly oriented downward at the mandibular body and backward at the mandibular ramus in both high pull and vertical pull. In case of medium pull it was oriented upward at the mandibular body and forward at the mandibular ramus. 3. The bending effect also turned out to be mostly oriented outward in case of high pull and medium pull, and inward in vertical pull. 4. At the mandibular body and ramus, the bending effect in the upward-downward direction and that in the forward-backward direction were found to be larger than in the inward-outward direction. 5. If and when we expect any correcting effect on the mandibular protrusion by means of the chin cup appliance, we can say sure as conclusion that high pull and vertical pull are more effective than medium pull.

In this study, a series of $LiNbO_{3}$ crystals with different [Li]/[Nb] ratios, congruent $LiNbO_{3}$ crystals with doped Mg and with Mg and codoped with Mn were grown by the Czocharalski method. These were investigated by UV and IR spectrophotometry. Stoichiometry dependences of the UV absorption edge and the $OH^{-}$ absorption spectra were studied with different [Li]/[Nb] ratios. The position of the UV absorption edge adn the shape and peak point of the $OH^{-}$ absorption spectra changed monotonously upto a critical concentration of Mg ions. The mechanism of the incorporation of Mg ions changes at this concentration. The decomposition of the $OH^{-}$ absorption spectra using a Gaussian lineshape function showed that in Li-deficient crystals the absorption spectra consist of five components in contrast to more or less perfect stoichiometric crystals which reveal to three components. On the basis of these results, the intrinsic and the extrinsic defect structure models in $LiNbO_{3}$ crystals were examined. The behaviour of $\nu$ (OH) reflects the defect structure and supports the Li-site vacancy model as the intrinsic defect structure model and the corresponding extrinsic defect model. A brief discussion is also given of the behaviour of $\nu$ (OH) in $LiNbO_{3}$ crystals simultaneously doped with several kinds of impurity.
